I just bought a 120 gallon smoker on a trailer from Dave's Custom in Riverview Florida. It didn't have a fire box, so let the fabrications began. We cut the smoker off the trailer and turned it around. We also extended the fenders out 6 inches. Using the pit calculator we are constructed a fire box, cut the end off, and the steel plate will also be a water pan. Here are a few pics of the work so far.






 
Morning.......

120 gallon smoker = 27,720 cubic inches...
FB/CC opening and area under the RF plate.... 27,720 x 0.004 = 110 ish square inches
FB air inlets..... 27,720 x 0.001 = 28 square inches.... and add an additional opening, directly across from the FB/CC opening, about 3-4 square inches..

I'm assuming you used Feldon's calculator.... Whatever calc. you used.... check your values with the ones I provided....

Take your stack diameter and length into consideration. It all works together as a system to create, use and evacuate heat/smoke.
